Walkthrough

The changes made in the pull request involve updating the s:to_slash_windows function in the autoload/fern/internal/filepath.vim file. The function now splits input paths using both backslashes (\) and forward slashes (/), improving its capability to handle different path formats on Windows. The filtering process for empty components remains unchanged, and the final output still concatenates non-empty components with a forward slash (/), with a prefix for absolute paths.

Objective	Addressed	Explanation
Reveal doesn't work with slash (/) separated path on Windows ( #478)	✅

🐇 In the land of paths, both slashes unite,
A function enhanced, making coding delight.
With each little hop, we handle with care,
Windows now smiles, no need for despair!
So let’s celebrate, with joy we shall sing,
For paths are now merry, let the code bring! 🎉

Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  -- I pushed a fix in commit <commit_id>, please review it.
  -- Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  -- @coderabbitai generate unit testing code for this file.
  -- @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  -- @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  -- @coderabbitai read src/utils.ts and generate unit testing code.
  -- @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  -- @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

Line range hint 9-12: Consider updating fern#internal#filepath#from_slash for Unix systems

The fern#internal#filepath#from_slash function currently calls s:to_slash_unix for Unix systems, which might not be the intended behavior. Consider creating a dedicated s:from_slash_unix function or verifying if the current implementation is correct.

function! fern#internal#filepath#from_slash(path) abort
  return g:fern#internal#filepath#is_windows
        \ ? s:from_slash_windows(a:path)
        \ : s:from_slash_unix(a:path)  " This function doesn't exist yet
endfunction

Line range hint 48-51: Consider updating s:from_slash_windows for consistency

The s:to_slash_windows function now handles both backslashes and forward slashes, but s:from_slash_windows still only splits on forward slashes. For consistency, consider updating s:from_slash_windows to handle both slash types as well:

function! s:from_slash_windows(path) abort
  let terms = filter(split(a:path, '\\/'), '!empty(v:val)')
  let path = join(terms, '\')
  return path[:2] =~# '^\w:$' ? path . '\' : path
endfunction

This change would make the behavior more symmetric and robust.

43-43: Excellent modification to improve path handling on Windows

This change effectively addresses the PR objective and the issue mentioned in #478. By modifying the split function to use both backslashes and forward slashes as delimiters, the s:to_slash_windows function can now handle Windows paths regardless of the slash type used.

Key improvements:

1. Increased flexibility in path handling on Windows.
2. Resolves the issue where the reveal function didn't work with forward slash separated paths.
3. Maintains consistency with the function's purpose of standardizing path formats.

The change is minimal, targeted, and doesn't introduce any apparent negative side effects. Great job on implementing this solution!
